This piece is from my original collection and used to be about three times larger. It flakes off in the hand. It also has the brightest sheen of any hemetite I have. It has been dropped several times and the smaller fragments given to pebble pups. |

It contains 3 1/2 teeth (plus a tiny fragment of a root from a fourth) in a section of jawbone. The teeth are about the same size as my molars but have a single inside and outside point each. It was #9 in my original collection (I wish I could find the index cards from it) and is one of the few I have left. It was a gift from the Grand Rapids Rock and Mineral Society for being the youngest first time visitor at the club meeting where I received it. |
